Hello,
I did an update on my laptop this morning, qt got updated to 5.11. Since then it seems that qt application are not following my GTK themes anymore. My desktop is Gnome.
I cannot copy/paste between application in qt and gtk
Any idea how to debug this ?

I confirm, all apps are broken now.

Similar issue here, okular behaves wired (stuck on top left corner, repainting issue all over the place). I use Gnome 3 on Wayland.

Downgraded to Qt 5.10.1 and things are running fine again. It seems that with Qt 5.11 applications get started with the Wayland backend by default, which presumably leads to the issues.

If that's causing the issues, exporting QT_QPA_PLATFORM=xcb environment variable should force qt applications to use X11 backend as a workaround.
EDIT. Alternatively you could just remove qt5's wayland backend by removing the qt5-wayland package.

I'm in xorg (because of nvidia) and do not seem to have these issues.

Indeed, both variants fix the issue with Okular and Qt 5.11 for me, thanks!

what is missing to have qt 5.11 work properly with Wayland ? is it just upstream support that is partial or it is some missing config/packages on my pc ?
